A pure titanium nanoscale oxide layer nanoprober precision detection method

Abstract

The application discloses a pure titanium nanometer scale oxide layer nanometer probe precise detection method, which comprises the following steps: S1, preparing a titanium sample to be measured, and pretreating the titanium sample to be measured to make the surface of the titanium sample to be measured smooth; S2, selecting multiple test points on the surface of the titanium sample to be measured and marking the test points, using a pressure head of a nano indentation instrument to make an indentation on the marked test points, and obtaining surface indentation data; S3, selecting multiple test points on the cross section of the titanium sample to be measured and marking the test points, using the pressure head of the nano indentation instrument to make an indentation on the marked test points, and obtaining cross section indentation data; S4, summing up the maximum contact depth in the surface indentation data of each test point and taking an average value, and marking the average value as a; summing up the maximum contact depth in the cross section indentation data of each test point and taking an average value, and marking the average value as b; and taking a difference between a and b to obtain an influence value of the oxide layer on the titanium surface. The application can simply and quickly evaluate the influence of the oxide layer on the titanium surface by using the nano indentation method.
